The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the table for Lakey Pipe.
We've got a cracking run of surf kicking off straight away. The wind is locked in from the ESE to SSE, giving us clean, cross-off conditions for the whole first week. It's looking very consistent.
The standout stretch starts Friday the 28th of August. We're looking at a solid 8ft SW groundswell with a very long 17-second period. The combined energy is meaty at 4343 (moderate to strong). This is proper reef-break territory with that long period, and it will be reeling down the reef in classic Lakey form. The water temp is a balmy 80°, right on the money for this time of year. This is expert territory at this size, and with the consistency and "often" crowds, you'll want to be on your game.
That swell holds through the weekend, dropping from 7ft on Saturday down to 5ft by Sunday, all with clean, light breezes. It eases a bit into Monday the 31st with a 4ft to 5ft bump, but that period stretches back up to 19 seconds – super long. That'll be offering plenty of power on the sets at Lakey Pipe, just with longer waits between them.
Tuesday the 1st of September sees the swell bump back up over 7ft, and we're into a solid run of 7ft+ days right through the middle of the week, with that clean cross-off flow. It's a fantastic run for any intermediate to expert surfer who knows the lineup.
After a slight dip on the 4th and 5th of September, the energy picks up again. Another strong pulse arrives around Sunday the 6th of September, with a 6-6ft SSW swell and light winds. Then Monday the 7th of September brings a 7ft SW swell in the afternoon – another top-tier day for the more experienced crew.
Looking into the second week, things get a bit dicey. The promise is still there – we see a 7ft SW swell on Friday the 11th of September, but the wind swings more southerly and turns cross-shore, putting a bit of chop on the face. The energy numbers are huge (5529), but the quality dips.
Then we hit Saturday the 12th of September. Swell pumps up to 12ft with a 17-second period – massive groundswell. The combined energy is pumping at 6719 (strong). But here’s the honest truth: that’s too big for Lakey Pipe. It’s a beast only for the absolute elite, and even then, it might just be a washing machine. The light offshore wind is a tease; it will be clean, but the sheer size and power will make it a wall of white water for most.
Overall, the first week is your window. The absolute best of the best is Friday the 28th of August and Monday the 7th of September. They've got the size, the period, and the perfect cross-off wind giving you those clean, hollow rights. Don't sleep on it.
Rusty.

Information about the Lakey Pipe Surf forecast
The above surf forecast table for Lakey Pipe provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Lakey Pipe can be found by selecting the local surf guide option on the grey menu. Our Lakey Pipe surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Lakey Pipe) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Lakey Pipe may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
